' CURTAIN FOR LQCOMOTIVE-CABS.

Application filed November 9,1920; Serial No. 422,928.

To all whom it may concern; i

Be it known that I, HERBERT S. THOMP- soN, a citizen of the United States, and a resident of Peekskill, county of Westchester,

and State of New York, have invented certain new and useful Improvements in Curtains for Locomotive-Cabs, of which the following is a specification. I v I My invention relates to an improvement in curtains to be attached to the rear of locomotive cabs and an object thereof is the provision of an improved form of curtain and an improved method of carrying the same in place on the cab.

I am aware that curtains have been attached to the rear of locomotive cabs prior to my invention but the curtains as now constructed and as now attached to the cab possess certain disadvantages which it is an object of my invention to overcome. The curtains now employed are usually of canvas and merely nailed to the top of the loco motive cab. The curtains, of course, are frequently wet and when in this condition are usually folded back out of the way, which causes them to decay. For these reasons the curtains must be frequently replaced.

A further disadvantage of the curtains as now used is that they have holes burned in them by the pokers and other tools employed by the engine crew.

In the accompanying drawings wherein I have illustrated an embodiment of my invention,

Figure 1 shows in elevation my improvedcurtain attached in place to a locomotive cab;

Fig. 2 is a part sectional side elevation of the cab of Fig. 1;

Fig. 3 is a part sectional end elevation of the apparatus of Fig. 1 with certain of the parts very much enlarged;

Fig. 4 is a view taken substantially on the line 44 of Fig. 3;

Fig. 5 shows a section of a reinforcing strip employed, this view being taken substantially on the line 5-5 of Fig. 3; and

Fig. 6 is an enlarged sectional view of the locking means employed for holding my curtain in adjusted position.

Referring to the drawings in detail, 1 designates a locomotive cab, looking at the same from the rear, this cab being provided with panels 2 and 3 and an opening 4. It is at this opening that I provide my improved curtain designated as a whole 5, this curtain being in the form of a strip of fire-proof material 6 secured at its upper end to a roller 7 mounted adjacent the top of the opening 4:- The strip 6 is provided at intervals with relnforcing strips 8 (see Fig. 5) each end of each of these reinforcing strips preferably being provided with guide rollers 9..

These rollers are adapted to travel in channels 10 secured to each side of the opening 4:. The curtain when being raised is rolled upon the roller .7, this roller being rotated in a,

direction to cause the curtain to be rolled up by means of a spring 11. In order that the curtain may be held in any desired position I provide locking means illustrated in detail in Fig. 6. This locking means comprises slidable, transversely movable bars 12 and 13, these bars passing through members 14: secured at each side of the curtain at the bottom thereof, being forced outwardly by springs 15 and when forced outwardly engaging holes 16 provided at intervals in the channels 10. The inner ends of the members 12 and 13 are bent up at 17 and 18 to receive cables 19 and 20 which are secured thereto and which are led through an eye 21 secured to the bottom of the curtain and then upwardly to the top of the opening 4.

It will be apparent that if it be desired to release the curtain to allow the same to roll up out of the way, it is merely necessary to pull on the cables 19 and 20 which will cause the locking members 12 and. 13 to be retracted out of engagement with the holes 16 in the channel 10 whereupon under the action of the spring 11 the curtain will be automatically rolled up.

In order that the curtain may not dete- I STATES PATENT ce.

riorate, should it be left rolled up in a wet condition, I mount the roller 7 in a hood 23 adapted to be steam heated by a pipe 24 which may be connected to the boiler of the engine in any suitable manner.

From the foregoing it will be seen that I have provided a fire-proof curtain of novel construction and which is connected to or secured in place on the cab of the engine in such, 'a manner as to enable the curtain to be easily raised and lowered and in such a manner as to prevent decay of the curtain due to the same being rolled up when wet.

It will be apparent also that by providing a curtain of fire-proof material danger of burning holes in the curtain with a poker or other tools employed on the cab is eliminated. i V

What I claim isi 1. A curtain for locomotive cabs comprising a body portion of fire-proof material reinforced at intervalsthroughout its length,

r a roller for receiving the curtain, a sprlng for rotating said roller to rotate the same and causethe curtain to be rolled up and a heated chamber within which said r'oll'er is mountedi 2. .In combinatlon, a curtain, a roller for pressed locking members at the bottom of said curtain adapted to hold the curtain in desired position, "and means extending from said locking members to a point adjacent the top of the curtain operable to release said locking members to permit the curtain to be rolled up upon its roller within the said heated hood.

and means for raising the curtain and storing it within said hood.

4:. In a locomotive cab having an opening,

channels at each side of said opening, a

heated hood at the top of said opening, a roller Within said hood, a curtain for said opening, rollers attached to said curtain and traveling in said channels to guide the cur tain, and locking means at the bottom of the curtain adapted to cooperate with said channels to maintain thecurt'ain in any desired position relative to said opening.
